To all whom it may concern.-

Be it known that I, HARRY S. BERGEN,

Y citizen of the United States, residing at Day ton in the county of Montgomery and State of ()hio, have invented certain new and riseful Improvements in Perforatingitiachinee, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in perforatingqnaohines, more particularly to that class of such machines which are used to reproduce the so-callod perforated music-- sheets which are used in pianolas and analogous mechanical playing instruments.

In general construction my machine crn bodies a series of keys which control the 'operativeness of a corres ending series of unches, which punches w on operated porlhrate the music-sheet which is fed between the punches and the corresponding dies, so as to produce in said music-sheet a series of perforations corresponding to the various keys which have been depressed; and. if it is do sired to reproduce a particular mnsic-slwot which is being used in a ianola the pianola is simply moved up to .tlie kevboard of my machine and the operation of the pianola will cause the depression of the various keys of my machine, and with the proper speed of feed of the paper to be perforated there will result a reproduction oi'the pianola music-- sheet in perfectly duplicate form. Such machines are at present well known as Far-as the general mode of operation of the some is con corned; but it is the object of my invention a to simplify the mechanism of such machines and to insure a possibility of rapid and accu rate movement of the various punches, and

thereby secure an absolute reproduction copy of the music-sheet, which of course is most essential in the manufacture of music- .leets in this manner.

Referring to the accompanying drawings, Figure 1 represents a vertical cross-section of my machine. Fig. 1 represents a detail end elevation of one of tho punch-controlling arms. Fig. 2 represents a top plan view of a portion of my machine, showing only a portion of the keyboard. Fig. 3 represents a dctail elevation of the gears for feeding the innsic-shcct.

The keyboard of my machine is mounted upon any suitable casing 10, within which casing is contained the supply'roil 11 of the music-sheet, said n1usicsheet bcing'led over guidmrollers 12 and across a transverselyextemling (lie-block l3 and then led onto a windingroll 24, which is mounted upon a shaft 15, supported by brackets if oxtonding from the casing ll), the feed of this paper being produced in the manner later to be described.

The keyboard oi' the machine is made in the regular pianolorto style, and since the construction of all the keys is 'nactically the some I shall des ribe only ulu The key 2 is pivoted upon :1. transverse shaft 13!, which is supported by upright stamlzmls 22, extending upward from the cusing'll]. ()n the under side of the key is a link 23. which is pivoted at its lower end to a lever 12%, pivoted at its middle portion upon a transverse shaft supported between supports so, extondine upward from the (rising Ill. The rearward end of this lever .24 is formed with a slot 27, in which plavs a pin 28, formed on the fol-word end of a bell'crank lever 29. which is pivoted upon a transverse shaft 30, extending ctween supports 30, extending upward from the casing 10. The upper end oi this bell vranlslsver 29 has attached to it apnnchcontrolling arm 31, this boll-(rank lever 29 and the pnnch contl'olling arm 31 being normally drown forward by means of a spring 32. The rcnrwnrd and lower end of the arm 31 is formed with a cylindrical slot 33, the shape of which is shown in Fig. 1*, and into this slot projects the rounded head 34 of the reciprocntory punch 35, the shape of this head and the slot obviously being such that the orrn 31 can be reciprocated forward and rear ward independently of the. punch; but the vertical movements of the arm 31 will carry with it the punch. Extending upward from the arm 31 is a retracting-arm 36, which is bent horizontally rearward and extends over the transverse shaft 3?, which shaft is formed with an elon ted eccentric portion 38, the purpose of w 'ch is to serve in reciprocating the arms 3 l, and thsreb the various punches 35, in the manner to be eter described. The rearward u per surface of the arm 31 is cut away slightly, as at 39, so that in the normal forward position of the arm 31 this cut-away ortion rests in under the eccentric-shaft 38;

ul; when the arm 31 is carried rearward in the manner to be described the raised upper surface 39 of the and 31 will now be in the path of the eccentric-shaft 38, so that therotation of the shaft 38in the manner to be described will cause. the arm 31 to be carried downward. The punch 35 is suitably seated.

ICC

in it punch-block 40 and is provided with s sninll collar 4 l against which presses a spring 42 for holding the punch noruiull in upward position, and below the punch is the dieblock 135, formed with the die 43, into which the punch penetrates when rcciprocuted to per forate the music-sln-et.

First to the right-hand end of the shaft 37 (see Fig. 2) is a pulley-wheel 50, which is iii; mnged to be driven by a belt so as to ini pin-t movement to the wheel 50 in the direc tion shown by the arrow in Figs. 1 and 2. Also fttSt to this shaft 37 and adjacent to the wheel 50 is n singletooth disk 51, the tooth 52 of which engages the teeth of the locking gear 53, suitably iournaled on. n stub-shah 54, and this rear 53 meshes with :1 larger grin- 55, join-nailed upon a stub-sl'iaft 56, which ex tends laterally from the support 57, in which su )port 57 one end of the shaft 37 is journnled, the other end of the shaft 37 being journnlcd in a similar supiiort extending upword from the opposite side of the casing If), so that these two supports act as bearings for the rotary shaft 37 The genr wheel in turn ineslies,\ritli the larger gear-wheel 16', which is journnled upon the shaft 15 and can ries the WithllI1; f--lull!l' M for the music-sheet. As shown in Fig. 1%, when the shaft 37 is rotated in the direction of the arrow the tooth 52 engages the gear-wheel 53 at each rcvolution snd through the intervening gears turns the gear 16" in the direction shown by the arrow, so as to advance the paper a certain disturn-c at each revolution of the shaft 37, the feed being of course intermittent and the gears being locked, so as positively to prevent movement of the paper during the period of time in which no feed is takirg place, this locking eiiect being produced y'thc rotst ing of the disk 51 upon the lockingsurfsces 58 of the locking-genr 51), end the notch 59 of the dish 51 permitting the rotation of the gear 53 by the single tooth, it being understood, of course, that at the time the single tuulli 5:3 is brought into position to engage the gear 53 the notch 59 is simultaneously brought into position opposite one of the points of the stsr-wheel-loeking surfaces 58, so that this point will project into the notch 59 when the gear 53 begins to be turned by the tooth 52, the notch 59 thus affording sufficient space for the turning of this star wheel upon its axis, and as soon as the tooth 52 has passed from engagement with the gear 53 the locking-disk 51. again engages closely upon the periphery of the looking-surface 58,

which, is adjacent to the point of the surface which has previously entered the notch 59. As will be seen from the position of the crunshnft 38 in Fi 3, the feed of the paper will take place'whi e the cum-shaft is in its upper position, during which time no reciprocation of the punches is taking place, since the punches are reeiproeeted by the cam-shaft being rotated to its lower position to strilm the controlling-arms 31 in ruse such arms are reciprocated rearward by the keys.

In the opemtion of the machine a pinhole containing the music-sheet to be reprodurrd is moved u to the keyboard of my nmchine and the pn ey 50 and shaft 37 u re given s rotary movement by any suitable mechanical or electrical means, so as toferd the paper of the music-sheet to be reproduced at practically the some speed as the pianola musicsheet. Then when itnyhnmmerof the pianola, Stf'lklm the key 20 and dc n'esses the same the depression of the link 23 rocks the lever 24 about its pivot .25, and thereby actuates the ln'llwrnllli lever 29 to carry the controllingnrin 31 rearward, and thcrolrv the raised portion 39" of the upper surface of the arm 31 is carried into the path of movement of the ec centric-shaft 38, so that said shaft in its ro terry movement strikes the arm 31 and forces the same downward, thereby carrying down ward the punch 35 and causing the some to rforatc the paper, and when. the'erccntriooh; ft 38 has rotated far enough. to withdraw in eccentric portion from contact with 'the raised portion 39" the spring 42 of the punch 35 forces the punch upward and withdraws the some from the paper, of course also carrying u iward the arm 31; but in case the punch should for some reason stick and tend to remain in its depressed position the eecentrio-shaft in its continued rotation upon reaching its upper position strikes the re tracting-nrm 36 of the arm 31 and positively restores the arm and. punch to normal upard position. if the key 2U still remains depressed during the continued rotary movement of the shaft :38, the shaft upon again running to its downward position will of" course again strike the raised portion 39" and will again reciprocate the punch downward through the paper, and since the paper in the meantime has been. fed along by the intermittent feedebo've described the punch now makes it new perforation n the paper slightly iniedvenre of the previous erforation, the el gtent of the intermittent eed be ilig such that with these successive reciprocations of the punch caused by holding the key 20 depressed the punch will cut out a, slight portion of the paper each time in advance of the previous perforation, so that the resultant effect is the cutting of a slot in the paper similar to the slot contained in. the pin no a-inusie. Of course when the key 20 is released to return to normal position the s )ring 32 pulls the arm 3] forward, so that tie cut-away )ortion 39 is in the path of movement of the shelf t 38, and-the shaft ow crates neither u on the arm 31 to rpck i w some downwnrr, nor upon the retrtuetim arm 36, so that the arm remains stationary without there being any reciprocation of tin punch.
